Response to Interrogatory Seeking Conception and Reduction to Practice Dates May Not Identify Voluminous Documents

The court granted defendant's motion to compel further interrogatory responses regarding conception and reduction to practice. "⁠[Defendant] concedes that [plaintiff] has narrowed the dates (indeed, [plaintiff] has said it will use the filing date for [one patent-in-suit]) but the issue of [plaintiff] citing 'hundreds of documents' with no explanation of their relevance. . . . [Plaintiff] shall prepare a document entitled 'Date of Conception' as to the [other patent-in-suit]. The document shall list the documentary support for its date range and attach the relevant documentation -- limited to 10 documents -- which shall be highlighted. [Plaintiff] shall do the same for 'Reduction to Practice.' These documents will serve as a base line for conception and reduction to practice. Should [plaintiff] choose to amend the dates at some later date, it will have to be based on newly discovered evidence."
